Granted: 2001-01-09
Abstract: A multiple inshot-type gas burner structure is formed from a pair of facing, intersecured stamper sheet metal plates. A spaced plurality of parallel,rectangularly cross-sectioned burner bodies are defined by facing triangular indentation pairs in the plates and have, at front outlet end portions thereof, side indentations which serve to mix air and gaseous fuel received at rear end portions of the burner bodies, and to divert a portion of the fuel/air mixture into crossover channels intercommunicating front interior portions of the burner bodies. The crossover channels have central arcuate closed portions that cooperate with progressively sized standoff dimples extending between opposite wall portions ofthe channels to provide an even crossover flame pattern along the outlet slot section of each channel. At the outlet end of each burner are four flame retention tabs which are transverse to the flow axis of the burner body and serve to prevent induced secondary combustion air from causing undesirable main flame liftoff. Originally rectangular inlet end portions of the burner bodies are laterally inwardly deformed to define generally circular sections that receive and firmly hold hexagonal gas supply orifice fittings mounted on a gas supply manifold pipe. Immediately forward of these deformed circular sections a plurality of primary air inlet openings are formed through the burner body walls.

Filed: 1997-11-28
Granted: 2006-05-02
Abstract: This invention provides a data bit redundancy method and apparatus that permits the replacement of faulty bitlines on a data bit basis as opposed to a column address basis. This invention provides a semiconductor memory device having memory cells arranged in columns and rows. Normal local data lines are connected to a global data line via a first switch. A redundant memory data line is connected to the global data line via a second switch. A control generating first and second control signals are coupled to the respective first and second switches for operating the switch in response to a status of a fuse component, whereby when the fuse is intact the normal data lines are connected to the global data line and when the fuse is blown the redundant data lines are connected to the global data line, thus not requiring additional redundancy address decoding circuitry.

Title: Pulsed-signal magnetomechanical electronic article surveillance system with improved damping of transmitting antenna
Inventor: HERRING RICHARD L
IPC: G08B13/24
Filed: 1997-01-15
Granted: 2003-07-08
Abstract: In a pulsed-signal magnetomechanical electronic article surveillance system, a single transmit circuit (16) is used to drive two or more parallel-connected interrogation signal transmitting antennas (18-1, 18-2). One or more switchable damping circuits (34-1, 34-2) are provided in series with the antennas to promote rapid damping of the interrogation signal at the end of each signal pulse. The damping circuit(s) are situated to provide damping in the loop(s) formed by the parallel connected antennas. Each switchable damping circuit is formed of a resistance (38) connected between a respective antenna and a terminal (36-1, 36-2) of the transmit circuit, as well as a switching element (40) connected across the resistance. The switching element is maintained in a conducting condition during each signal pulse and is open-circuited at the end of each pulse to bring the resistance into effective damping connection with the transmit antennas.

Title: Ink-jet printing apparatus
Inventor: KOITABASHI NORIBUMI
IPC: B41M5/00
Filed: 1998-12-23
Granted: 2003-07-29
Abstract: Upon performing printing using a dye ink and a pigment ink and in addition a treatment liquid making those inks insoluble, two kinds of inks consisted of the pigment ink and the dye ink are used.  After applying the pigment ink on a printing medium, the dye ink is applied overlaying with the pigment ink.  After mixing these inks on the printing medium, the treatment liquid which makes the inks insoluble, is applied.  In the alternative, a mixed ink in which a pigment ink not requiring a dispersant and the dye, is used.  After application of this mixed ink on the printing medium, the treatment liquid which makes the ink insoluble, is applied. Therefore, problem of "crack", "soaking out", "overflow" or lowering of OD value which can be caused upon reaction of the pigment ink and the dye ink or the mixed ink with the treatment liquid, can be solved to achieve high quality printing.

Patent CA-2260011-C (CA)
Inventor: PAGGI JOHN
IPC: H04Q3/66
Filed: 1997-06-26
Granted: 2003-01-07
Abstract: A method of operating a switched communications network redirects certain types of messages away from the switch to free up switch resources for other messages, thereby decreasing the size of switch needed or delaying necessary switch size upgrading. Messages are redirected by intelligent concentrators that can connect certain types of messages to their destinations without routing them through the switch. For example, messages between an origination and a destination connected to the same concentrator need not be sent through the switch. Similarly, messages between originations and certain high-volume, long-duration destinations such as data service gateways can be connected directly without passing through the switch. The intelligent concentrators communicate with the switch on a control channel so that the switch remains aware of the status of each origination or destination (e.g., so that it knows not to attempt to route messages to an origination or destination that is in use).

Title: Carburetor having extended prime
Inventor: KLEIN THOMAS G
IPC: F02M1/16
Filed: 1999-05-05
Granted: 2003-12-30
Abstract: The present invention involves a carburetor having an extended prime fuel chamber for gasoline engines. The carburetor includes a carburetor body having a throat, a fuel bowl, a conduit extending from said fuel bowl to said throat, a variable volume primer chamber communicating with said bowl through a priming passage, and an extended prime fuel chamber. The extended prime fuel chamber delivers additional fuel from start-up through warm-up periods of the engine. The extended prime fuel chamber communicates with the throat extending to the engine and communicates with the bowl containing fuel. The extended prime fuel chamber is arranged such that, after activation of a priming bulb, fuel from the carburetor bowl is directed into the throat through a nozzle tube and also into the extended prime fuel chamber through a prime fill passage. Once the engine fires, the fuel in the extended prime fuel chamber then is also directed into the carburetor throat through an extended prime fuel passage disposed at a lower position in the extended prime fuel chamber than the point at which the prime fill passage connects to the extended prime fuel chamber.

Abstract: Tray packs (12) are packs made of cardboard or the like which are open at the top and have side walls, namely longitudinal walls (13, 14) and transverse walls (15, 16), of a low height. In order to improve the dimensional stability of the tray pack (12), upright corner supports (25, 26) which are angled in cross section are provided in the region of corners, the height of said corner supports corresponding approximately to the height of the individual packs or articles. A base wall (17) comprises base tabs, namely transverse tabs (18, 19) and longitudinal tabs (20, 21), which correspond, in shape and size, to recesses (29, 30) which are formed above the side walls (13 .. 16) in conjunction with the corner supports (25, 26). This means that blanks for the tray pack (12) can be produced in a largely waste-free manner from a continuous material web.
